The Audigy SE sound card has MIDI out capability throught soundfont loading.
But asfxload does not work with ca0106. So no way to load midi instruments at my knowledge. This is a shame because Midi out port seems to be configured correctly by ca0106, as may be seen from a secuencer MIDI programa as seq24 for example.

Combination of dmix and surround51 working for SB Audigy SE at last?

I'm capturing sound now with this card. I followed the instructions on: http://alsa.opensrc.org/Ca0106 and the mic works! remember set Digital in to "i2s in" an turn up mic volume. Works with a SB0570.
